Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31573996, here are decompositions:

29 + 31573967 = 31573996
137 + 31573859 = 31573996
149 + 31573847 = 31573996
173 + 31573823 = 31573996
239 + 31573757 = 31573996
317 + 31573679 = 31573996
353 + 31573643 = 31573996
569 + 31573427 = 31573996

Showing the first eight; more decompositions exist.
